BmnnR-sIcKLn GUARD on TClOTH.

Be it known that 1, DAVID F. BARNES, a-

citizen of the United States, residing at Coleridge, in the county ofCedar and State of Nebraska, have invented anew and useful Binder-SickleGuard or Tooth; and I do hereby declare the following 'to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains't-o make and use thesame. v

This invention relates to a new and useful improved sickle bar guard ortooth. As far as known such guards have been made sharp and pointed, andit has been found that they are continually catching or piercing thestalks, thereby clogging the binder 'or re tarding the same. Such guardswhen catch ing or piercing the stalks causes the same to be bentdownwardly, in which case. the binder will pass over the stalks, withoutthe sickle bar cutting them.

Therefore, it is the aim of the resent invention to overcome theabove'di cult-ies or disadvantages, by providing a guard having arounding point, .so that the stalks will be deflected to one side of theguard.

Another object-of the invention is to. so

construct the guard adjacent the rounded ends as to provide meansforming abut-ments to be engaged by the stalk when deflected to oneside, so that the sickle bar will easilysever the same.

In practical fields the details of construction may be subjectedto'alterations, falling within the scope of What is claimed.

The invention comprises further features and combination of parts, ashereinafter set forth, shown inthe drawings and claimed.

In the drawings :-Figure 1 is a view showing the "improved guardconstructed in siccorclance with the invention. Fig. 2 is a I plan view,showing. the position of the stalk after the same has been deflected.Fig. 3 is a sectional '.view' longitudinally through. the guard. Fig. 4is a transverse sectional view, on line 4-4 of Fig. 1. .Fig. 5 is a planview showing the abutment omitted. Fig. 6 is a sectionalview'longitudinally through Fig. 5.

Referring more especially to the drawings, 1 designates the guard, theunder surface or portion of which as shown at 2 and 3 is V- shaped, sothat the guard will slide over the soil as the binder frame (not shown)vi- Application filed January 17, 1914. Serial No.'8 12,614. 1

brates. That is, as the binder (not shbw'ri) passes over the soil, theframe carrying the sickle bar vibrates, andas it vibrates down 'wardlythe V-shaped lower portion ofthe easily edge 4; shown in the sectionalview.

Instead of'constructing the guard sharp and pointed, the same isrounded,"as shown at ,5, 6 and 7 so that as it" comes in contact withthe stalk, the stalk is deflected to one side or the'other, and whendeflected, the same engages'the shoulder 8 on either side of the guard,which shoulder acts as an abutment for the stalk while the same issevered by the sickle bar 9, as shownin Fig. 2. In other words, it willbe seen in Fig. 2 that as the sickle bar 2 moves in the direction-of thearrow 10, the stalk is easil severed without forcing the stalk forwar lyof a I the guard, because the abutmentprevents it. .The sickle bar,moves in therecessedjportion' of the guard, under the cover 11 of theguard, the end 12 of the cover seats in a recess 13 of the guardand issecured in place as shown at l4,the end wall 15 of the recessoverhanging the end of the cover partially.

'In Fig. 5 the abutments are omitted, other. wise the structure issimilar to that shown in the other figures.

The invention. having been set forth, what is claimed as new and usefulis A sickle bar tooth guard comprising a body portion having. a recessfor the sickle bar to more. therein, the body portion of the guardhaving a roundedend and upon its upper surface ad acent said end arecess, a cover plate having one of its-ends secured in the recessadjacent the rounded end, the

end wall of the recess of the rounded end overhanging the end of thecover, the oppo-v site sides of the rounded end being drawn inwardly toformshoulders with which-a stalk contacts while being severed by the,

sickle bar. the guard adjacent the rounded end tapering downwardly andrearwardl'y. In testimony whereof I have signedmy name to thisspecification in the presence of two subscribing witnesses. l
